Events 2
Fired when the device orientation changes.
On Android, note that the application must have a heavyweight window or tab group open
in order to receive the orientationchange event. It is not necessary for the heavyweight
window to be the topmost window.
Almost all real-world applications will have a heavyweight window or a tab group. This is
only likely to be an issue if you create a test case or test application that adds an
orientation change listener from app.js without opening a heavyweight window.
| Event properties | Type | Description |
|---|---|---|
| orientation | Number | Orientation of the device. |
Fired when the device is shaken.
A shake gesture consists of a series of quick accelerations, and is represented by a series of shake events.
The timestamp property represents the interval between shake events. It is measured in
milliseconds on Android, and in seconds on iOS.
| Event properties | Type | Description |
|---|---|---|
| timestamp | Number | Time interval since previous shake event. On iOS, this value is 0 for the first shake event in a series. |
| x | Number | Acceleration along the X axis, in Gs. |
| y | Number | Acceleration along the Y axis, in Gs. |
| z | Number | Acceleration along the Z axis, in Gs. |
